Circle P has a radius of 14 feet. Circle Q has a diameter of 14 feet. What is the ratio of the circumference of P to the circumference of Q?

Respuesta :

Answer:

2:1

Step-by-step explanation:

Circle P has radius 14 feet.

The circumference of this circle is given by:

[tex]C=2 \pi \: r[/tex]

We plug in the radius to get:

[tex]C=2\pi \: \times 14 = 28\pi[/tex]

Circle Q has diameter 14 feet.

The circumference of this circle is given by

[tex]C=\pi \: d[/tex]

We substitute the diameter d=14 to get,

[tex]C=\pi \: \times 14[/tex]

[tex]C=14\pi[/tex]

The ratio of the circumference of P to the circumference of Q is

[tex]28 \pi: 14\pi = 2:1[/tex]
